Most people reading this do have a Lengio account. An account is required to use Lengio, so if you have been using the app you have one, and the sections below apply to you. You can delete it from inside the app in about thirty seconds, or by email if you no longer have the app installed — both routes are below and both reach the same place. If you are on Android, or on an older iPhone release from before accounts arrived, you may not have one: see If you do not have an account.
This is the fastest route and it needs nothing from us.
The request takes effect immediately in the app: you are signed out on that device and the account can no longer be used to sign in anywhere. There is then a 7-day grace period during which you can change your mind — sign in again with the same email address or the same Apple or Google identity within those seven days and the deletion is cancelled. After seven days it is executed and cannot be reversed.
We email you when the request is made and when it is executed, so a deletion you did not ask for cannot happen silently.
If you have uninstalled Lengio, lost the device, or simply prefer not to reinstall it, you do not have to. Email us and we will do it for you:
Send to [email protected] with the subject line “Delete my Lengio account”.
Send it from the email address the account uses if you can — that is how we confirm the request is yours, and it is the whole verification step. If you signed in with Apple and chose Hide My Email, send it from the address you use with your Apple Account and tell us; we can match the relay address to it. If you signed in with Google, send it from that Google address.
We do not ask you for a password (Lengio has none), a payment detail, an identity document, or anything else. If we cannot match your message to an account we will say so and ask one narrow follow-up question rather than guess — deleting the wrong person's account is the one mistake here that cannot be undone.
We acknowledge requests within 5 business days and complete them within 30 days, which is the statutory deadline under the GDPR and comparable laws. In practice this is usually done the same day. The same 7-day cancellable grace period applies, counted from when we action the request.
Deleted, permanently, when the request executes:
Kept, and why:
Backups. So that we can recover from a failure or a mistake, the account database is backed up three ways: Cloudflare's own rolling 30-day point-in-time history, a daily export we keep for 35 days, and one copy on a company computer deleted after 40 days. Deleted data may still exist inside those windows. It is never restored back into the live service, and it ages out on its own within 40 days at the outside.
Your progress on the device is a separate thing and deleting the account does not wipe your phone. Your photos and your Chat Coach conversations are only ever on your phone and we never had a copy of them. Your words, streak, review schedule and settings are on your phone and, while you are signed in with sync on, in the copy we hold against your account — and that copy is deleted along with the account. To clear what is left on the device, see section 5.
Deleting your Lengio account does not cancel a paid subscription, and we cannot cancel one for you. Subscriptions are billed by Apple or by Google, not by us, and only they can stop the billing. If you are subscribed, cancel it yourself before you delete the account — afterwards you will still have to, and you will no longer have the account to reach it from.
Refunds are also handled entirely by the store you bought from; we have no ability to charge or refund you. See our support page for the refund links.
An account is required on iPhone and iPad from the release that introduced them. You will not have one if you are on Android, where accounts have not arrived yet, or on an older iPhone release. In that case there is nothing on our servers to delete — your data is on your device and we never had a copy. Two controls remove it:
Two honest footnotes. If your device backs up to iCloud or to your Google account, a copy of Lengio's data may sit in that backup, which belongs to Apple or Google rather than to us — manage it in your iCloud settings, or in Android → Settings → Google → Backup. And on Android specifically, the random identifier the app attaches to anonymous usage statistics is included in Google's Auto Backup, so it can come back on a reinstall or a new phone rather than being replaced with a fresh one; you can stop those statistics entirely with Settings → Share Usage Data. Our Privacy Policy explains both in full.
Write to [email protected] and a person will answer. You can also ask us to export a copy of your account data before you delete it, correct something in it, or restrict what we do with it — those rights are described in section 14 of the Privacy Policy.
Lengio is published by Nexios Media LLC, an Illinois limited liability company (nexios-media.com), which is the data controller for the account data described above.
A note for reviewers. This page is the account-deletion URL declared for Lengio in the Google Play Console and referenced by the in-app Delete Account control. It requires no sign-in and no app installation to read or to act on.
